COAL-CART.

SPECIFICATION formingpart of Letters Patent No. 593,306, dated November 9, 1897.

Application fil d June 10, 1897. Serial No. 640,214. (No model.)

To aZZ whom it may 0071108770.

Be it known that I, FRIEDRICH D. F. MtiL- LER, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Coal-Carts; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to coal-carts; and its object is to provide an improved form of coalcart which may be easily operated and which will be simple in construction.

My invention consists of certain novel features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my improved coal-cart in its lowered position. Fig. 2 is a similar view in its raised position. Fig. 3 is a rear view. Fig. 4 is atop plan view. Fig. 5 is a top plan view with the body removed.

The numeral 1 indicates the frame of my cart, which is formed in the usual manner. WVheels 2 serve to support the same, and the cart may be provided with any suitable running-gear. The body 3 of my device is held upon the frame 1 by a series of levers to be hereinafter described. A partition 4. divides said body longitudinally into two parts, preferably equal. Doors 5 are held at the end of said body to normally close one or both of said portions. A chute 6 is held upon said end portion and is of the usual form for coalcart chutes.

In reference to the levers, which constitute one of the principal features of my device, a shaft 7 is mounted upon the frame 1, extending transversely of said frame. A gear 8 is carried upon the central portion of this shaft. A ratchet 9 is carried upon the outside thereof. A lever or handle 10 is firmly attached to said shaft. A pawl 11, carried upon the frame, is adapted to coact with said ratchet and hold the shaft in any position in which it may be turned. Rockerarms 12, firmly keyed to said shaft, are preferably mounted one upon each side of said gear. A lever 13 is held to rotate in bearings upon the front part of the frame, as at 14:. A segment 15 is formed upon said lever and is adapted to mesh with the aforesaid gear. A lever 16 is pivotally joined to the outer end of this lever and is connected with the bottom of the cart. Bars 17 serve to connect the lever 16 with the ends of the rocker-arms. Toggle-jointed levers 18 are held upon each side of said frame and are provided with stops 19. This is the construction upon the front end of the cart, and it is obvious that if the lever be turned the gear meshing with the segment will revolve the other lever and raise the cart. Furthermore, it is also obvious that the rods leading from the rock-shaft to the lever attached to the cart will assist the same in being forced up.

I will now describe the device used for raising the rear end of the cart. A shaft 20 extends transversely of said frame in a manner somewhat similar to the first transverse shaft. Upon this shaft are double rockerarms 21. Hooked bars 22 are held upon one of the ends of the rocker-arm. Suitable eyes 23 are held upon the frame at a proper point to engage said hook. A ratchet 24 is held upon said shaft outside of' said frame. A pawl 25 is held upon said frame to coact with said ratchet. Levers 26 are fulcrumed upon said frame, as at 27. Rods 28 serve to connect said levers with said rock-shaft. Guides 29, formed upon said cart, serve to receive the end of the levers and hold them thereon. It

is now plain that if the handle be turned the rock-shaft will pull up on the pivoted levers,;

which are preferably bent to enable this to be more readily done, until the back of the cart is raised, the ratchet acting to hold the same in position. If, however, it be desired to relieve the strain upon the ratchet, the hooks upon the other end of said rocker-arm may be hooked into the proper eyes and the ratchet released.

It is obvious that many minor changes may be made in the form of my device without departing from the material principles thereof. I do not therefore desire to confine myself to the exact form herein shown and described, but wish to include all such as properly come within the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a coal-cart, the combination with a frame, of a body portion carried thereon, a shaft extending transversely thereof, a gear held upon said shaft, a pair of rocker-arms held upon said shaft, a lever pivot-ally mounted upon said frame provided with a portion having the segment of a gear thereon adapted to mesh with the first-mentioned gear, levers connecting said lever with said body portion, rods connecting said rocker-arms with said lever, means for rotating said shaft, and means for holding the same in position, substantially as described.

2. In a coal-cart, the combination with a frame, of a body portion carried thereon, a shaft extending transversely thereof, a gear held upon said shaft, a pair of rocker-arms held upon said shaft,'a lever pivotallymounted upon said frame provided with a portion having the segment of a gear thereon adapted to mesh with the first-mentioned gear, levers connecting said lever with said body portion, rods connecting said rocker-arms with said lever, a lever held upon the end of said shaft, a ratchet formed upon said shaft, and a pawl carried on said frame adapted to coact with said ratchet, substantially as described.

3. In a coal-cart, the combination with a frame, of a body portion carried thereon, a shaft extending transversely thereof, a gear held upon said shaft, a pair of rocker-arms held upon said shaft, aleverpivotallymounted upon said frame provided with a portion having the segment of a gear thereon adapted to mesh with the first-mentioned gear, levers connecting said lever with said body portion, rods connecting said rocker-arms with said lever, a lever held upon the end of said shaft, a ratchet formed upon said shaft, a pawl carried upon said frame adapted to coact with said ratchet, and apair of toggle-joint levers carried upon said frame and said body portion provided with stops and adapted to hold said body portion in a raised position, substantially as described.

4:. In a coal-cart, the combination with a frame, of a body portion carried thereon, a shaft extending transversely thereof, rockerarms carried upon said shaft, levers fulcrumed upon said frame having their ends bearing against the body portion of said cart, slides formed upon said body portion adapted to receive the ends of said levers, rods connecting said rocker-arms with the free ends of said levers, a lever carried upon said shaft adapted to rotate the same, a ratchet formed upon said shaft, and a pawl held upon said upon said shaft, a pawl carried upon said frame adapted to coact with said ratchet, hooked bars attached to said rocker-arms, and eyes held upon said frame adapted to receive the end of said hooked bars, substantially as described.

6. In a coal-cart, the combination with a frame, of a longitudinally-divided body portion having end-gates for said divisions, of a shaft extending transversely of said frame, a gear carried upon said shaft, rocker-arms held upon said shaft, a ratchet held thereon, a lever held at the end thereof, a pawl held upon said frame adapted to coact with said ratchet, a lever pivotally attached to said frame provided with a segmental gear upon one portion thereof, said gear being adapted to mesh with the aforesaid gear, levers connecting said lever to said body portion, rods connecting said levers to said rocker-arms, toggle-jointed levers provided with suitable stops connected to said body and said frame,

a second transverse shaft provided with apair of double-ended rocker-arms, a ratchet held upon said second transverse shaft, a lever held thereon, a pawl held upon said frame adapted to coact with said ratchet upon levers fulcrumed upon said frame having their free ends resting against the body portion of said cart, guides adapted to receive the ends of said levers, rods connecting the opposite ends of said levers with the lower ends of said rocker-arms, hooked bars held upon the upper ends of said rocker-arms, and stapleeyes held upon said frame adapted to receive the hooks upon the ends of said bars, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
